Not merely has BMW electrical architecture changed over the last decade, but so gets the equipment to service them. The apparatus has evolved, the interfaces have changed along with the complexity of setup and employ.
Early tools
Within the 1990’s, the Group Tester One (GT1) was introduced. There was a few versions, like DIS Plus (stationary setup), even so the GT1 is easily the most common which is what’s going to be referenced here. The GT1 can be a portable device which contained a rechargeable battery. It features a touchscreen display screen for easy use. It contained software for Diagnosing and also had software called TIS (Technical Information Display) which is Service & Repair Information. Early versions of Diagnostics also contained software called Coding, Programming & Individualization (CIP). So in the same tool, you might Diagnose the situation, research how you can switch the component then carry out the needed initializations for the new part. Two interfaces were used: EDIC (yellow interface) along with the OPS (orange interface). Later versions with the OPS were called OPPS, since they carried additional diagnostics for the Byteflite system plus they were also yellow, but much larger than the EDIC. Authentic GT1s are stored on the portable touchscreen unit. There are numerous “cloned” units out there, adapted to operate over a PC. Either genuine or cloned, the interfaces work exactly the same and fasten through an Ethernet port.
Later versions with the GT1 software removed CIP, and moved it with a separate computer (for storage), but still accessible in the GT1. This new software was called Progman (short for Program Manager). This new software contained every one of the CIP functions and added latest features like multiple car programming and dual channel programming for every car (DIAGBUS and many bus simultaneously).
Third Generation equipment
Fast forward about 2008 if the Third Generation (3G) of kit was released: ISIS. The contents of ISIS are so large, that dedicated servers are installed on the dealership. A web based version is accessible for the aftermarket for their fee, called OSS. It can be bmw fsc tutorial. Together with the introduction of ISIS comes a whole new interface, called ICOM. Previous interfaces (EDIC & OPS) will not work with ISIS. ISIS includes a few parts, since it completely replaced GT1 & Progman. The principle section of ISIS utilized in the shop is called “ISTA”, which is often further categorised into two parts: ISTA/D for Diagnosing vehicles and ISTA/P for Coding, Programming & Individualization.
Comparison
GT1s can be found anywhere you want to, including eBay for cheap. BMW pointed out that the tool was easily cloned and sold worldwide. Many levels of security have been place into the development of ISIS to avoid this, in the resident servers and internet-based versions. Labeling will help you more difficult for non-dealer shops to operate about the newer cars. One could believe since GT1 was discontinued in ’09, you might keep using for a number of more years prior to the newer system became more available, however, BMW stayed one step ahead! Each time a car is programmed together with the new ISTA/P, it upgrades the software after dark a higher level what Program can recognize. Meaning, once a car has become updated with ISTA/P, you cant ever use Progman on it again, rendering the “cloned” versions useless with that particular car. Also, each time a new module is installed, the software that is pre-installed with that module can be newer when compared with Program can recognize, that may stop the entire programming process, forcing the car to be programmed by ISTA/P.
Just what exactly does that mean for the BMW owner? On account of the newer systems, many BMW owners can’t repair the cars themselves. Many aftermarket shops will also be sending the cars to dealerships consequently. However, not all aftermarket shops have fallen behind. You can find a select few of BMW specialty shops that stick to top of manufacturer technology, so that no car is beaten down! When looking for a spot to service your BMW, ensure they’re able to do ALL aspects of repair, including Diagnostics and CIP!
